The Detroit Lions have retained Jim Caldwell as head coach.

"After spending a significant amount of time together, it is clear that our football philosophies are very similar," new general manager Bob Quinn said Friday. "Consequently, I am convinced he is the right man to lead our football team moving forward.

"Jim's entire body of work is impressive. Not only did he lead the Lions to the playoffs his first season here, but when you look at how the players responded the second half of last season, under difficult circumstances, it's clear to me that this team believes in him and responds positively to his leadership."

Caldwell was hired by the Lions in January 2014 and immediately turned around the struggling franchise, going 11-5 in his first season.
